ShareCash - Am I Going Crazy?

So I just heard about Sharecash and decided to give it a go. But no matter what I do cannot upload any files. 2 different FTP clients, no firewalls, double checked credentials and settings... nothing. So I downloaded Flash and I'm still getting the original 'please download Flash' window as I was originally.

What am I doing wrong here? Is Sharecash a waste of my time anyway?

I heard stories about that site and I myself try to stay as far away from share cash as I can. I'm currently using ogads as there the best for mobile offers.
